This is correct, other than saying "just happens to be". As you are the one who determines what memory (and thus, the size of the memory) that dest points to, ensuring there is enough remaining space for the src string is your responsibility.

SVG not supported 3:02am Mon 3rd Oct, Christopher M.

Yes. You need to provide sufficient space for dest before calling strcat p() You can increase the space associated with a pointer, and copy its original data too, with realloc() but, of course, that requires the pointer to have fir...

Piggybacking on this thread as I had a related question... From what I understand, strcat p only works as intended when there just happens to be enough memory adjacent to the dest string where we can copy the entire src (plus ' 0'). If there happene...

It's hard to tell without looking at your system, but it sounds like there isn't enough space allocated in the destination array to hold the result. Remember, strcat doesn't contain any mechanism for allocating more space, so the destination has to ha...

Hi, I'm having an issue with my strcat p function where I'm getting an EXC BAD ACCESS code 2 error which occurs with the sample solution also. I've attempted to debug it and found that the addresses of dest and src are next to each other, so I'm assumi...

ANONYMOUS wrote Neither question requires a sorting algorithm. There are far simpler solutions (because you don't need to sort the data).

SVG not supported 12:09pm Mon 22nd Aug, ANONYMOUS

I'm looking at Labsheet 2 and questions 3 and 4 are about some sort of sorting algorithm. Which sorting algorithm would be the best to learn? Is it really worth it to learn a difficult but complicated sorting algorithm or is it enough if I settle wit...

A reminder that this Wednesday 17th is PROSH, so our lab at 10-12 on Wednesday morning will be cancelled, but we'll be back for the 2-4 afternoon lab https units CITS2002 info-prosh.php

Hello Juliana, I've found it a bit difficult to understand your question, so there may be some assumptions misunderstandings in my reply. Firstly, to help understanding, let's not say "C script". The C source code is text to be (correctly) compiled be...

I suggest that, when using C's standard I O formatting functions, that you use i instead of d when dealing with integers. For printf() there is no difference, but when reading input with scanf() i is a better choice as it makes the han...

It should be printf("Receives d x 50 cent coins n", i);

For the last question of the refresher tasks I have made it so that the 2D array that is pulled by the c file is randomised 10x20 per the question description, nested a loop so that it checks for rows and column to find the largest number and then on...

Hi, I'm trying to print an integer in between two strings but I'm getting an error that says "warning too many arguments for format -Wformat-extra-args (as attached below) but I'm not sure what I'm supposed to do. My code is as follows printf (" ...

You don't have to modify the code to accept multiple arguments in the sense that argvalue already contains all the arguments passed to the program. You can see this with the following program This program prints out all the arguments passed ...

ANONYMOUS wrote It actually says more than just "error", it explicitly reports the problem. In fact, the problem is detected and reported by the rotate program itself, not by the shell or any other systems program. You need to invoke the rotate program...

Hi Chris, Our first lab each week is at 10am Mondays (after the 9am lecture) and you should have sufficient knowledge to (at least commence) it after the previous week's lectures (and Friday workshop, if that helps you). But the the lectures and labs d...

At the risk of confusing things, Labsheet 1 is in Week 2. Should I have enough knowledge after Week 1 lectures and study to attempt this labsheet, or should I complete Week 2 lectures first? Thanks Chris

The Face-to-face Lab is on Wednesdays 2-4pm. The Online lab is on Thursdays, 2-4pm. For reasons explained on our unit's homepage, you can ignore the CAS times. Thanks for reporting the problem.

SVG not supported 6:53pm Mon 1st Aug, Haoxuan L.

Hi just want to sate a contradiction I noticed. It says there is a face to face lab session 2-4pm on Wednesday but on top left it says its online. This session also doesn't exist on CAS. What is the verdict?
